Despite the surge in oil reserves in the US, the world oil prices are increasing, but experts predict a decrease in the prices.

Accordingly, the December Futures’ Brent Crude Oil has gone up by 0.33 percent and reached $48.27 per barrel.

And the December Futures’ Light Sweet Crude Oil (WTI) has risen by 0.61 percent and made up $45.48 per barrel, reported RIA Novosti news agency of Russia.

Analysts maintain that the shortage of raw materials will cause pressure on oil markets.
